2nd Law of Thermodynamics for fast random processes

Krzysztof Gawedzki, ENS Lyon

I shall discuss a finite-time refinement of the 2nd Law of Thermodynamics for stochastic models of mesoscopic systems evolving in thermal environment. The result will be illustrated on the model of memory erasure process discussed in Sergio Ciliberto\'s talk and compared to that for a qbit undergoing a Markovian evolution.
